The leaders of Aldine and Houston ISDs have moved to shutter 23 schools over the past three years — decisions largely driven by enrollment losses tied to a confluence of demographic factors.
The number of babies born within Aldine and Houston ISDs fell by more than 10% between 2010 and 2020, according to Kinder Institute for Urban Research estimates. And thousands of families with young children are moving out of the districts or opting for charter schools by the time their kids reach kindergarten, with comparatively few new families moving in.
As birth, migration and charter school growth patterns increasingly force tough decisions about public school operations, a new analysis by the Kinder Institute for Urban Research’s Houston Education Research Consortium offers a first-of-its-kind perspective on how the demographic trends are driving recent swings in school enrollment.
The analysis uses state birth data and mapping tools to estimate how many children were born in each district annually between 2005 and 2024. It also examines the number of kindergartners enrolling in each district relative to local birth totals, a measure of family migration, charter school preferences and other movements.
Taken together, the two data points help explain recent enrollment patterns and offer a strong indication of future enrollment trends. Texas public school districts largely receive funding based on the number of enrolled students, with increases resulting in fresh spending to accommodate growth and decreases forcing cuts.
The figures particularly illustrate the enormous pressure on some school districts in Houston’s urban core and southern suburbs, as they face declining births and receive fewer kindergarteners than expected based on their birth counts. Aldine, Alief, Houston, Galveston, Pasadena and Texas City ISDs all saw enrollment drop by 9% to 16% between the 2019-20 and 2024-25 school years.
Other districts, meanwhile, have seen births rise and more kindergartners enroll than expected based on birth counts. They are largely concentrated in Houston’s northern, eastern and western suburbs.
“Districts have to adapt in some way to changing circumstances, and in places where they’re grappling with declining enrollment and funding, that can mean fewer options for students,” said Courtney Thrash, a Kinder Institute researcher who helped produce the estimates.
“That can look different in each school, but it could mean fewer choices in career and technical education programs, fewer electives and fine arts opportunities, or having to travel farther to get to school.”
Fewer families, fewer students
From the early 2000s to the mid-2010s, Houston’s unrelenting expansion meant virtually all local school districts grew alongside the region. But over the past decade, Houston-area districts have seen substantial fluctuations in births, family migration and other factors underpinning enrollment.
In and around Houston’s urban center, where housing is typically older and often more expensive, the number of births sharply declined as more families moved to the rapidly developing suburbs and younger adults moved in, according to Kinder Institute estimates.
The estimated number of births between 2014 and 2024 declined by 15% to 30% in several districts: Aldine, Alief, Deer Park, Galena Park, Houston, Pasadena and Stafford.
Estimated birth totals also fell across parts of Brazoria and Galveston counties, where residential development hasn’t been as robust as other parts of the region. Notable declines were seen in the Galveston (-27%), Pearland (-19%), Brazosport (-15%) and Clear Creek (-12%) school districts.
At the same time, many of those districts have struggled to keep young children in their jurisdiction, attract new families and get students enrolled.
For every 100 babies born in Alief ISD in 2018-19, about 51 kindergartners ultimately enrolled in the district for the 2023-24 school year, Kinder Institute estimates show. Districts with similarly low ratios include Houston (55 kindergartners for every 100 births), Galveston (69), Pearland (72), and Aldine and Pasadena (75).
No stopping growth
By contrast, birth counts and in-migration have spiked on the region’s north side and in exurban communities targeted by developers building large, less-expensive housing.
Births jumped by 17% to 67% in Montgomery County’s largest districts: Conroe, Magnolia, Montgomery, New Caney and Splendora ISDs. Several districts on the farther outskirts of Houston saw similarly large increases, including Barbers Hill, Waller, Crosby and Lamar.
Many of those districts also saw an influx of families with young children, resulting in 120 to 200-plus kindergarteners enrolled in 2023-24 for every 100 babies born in the district five years earlier.
To avoid overcrowding, many of the fast-growing districts have continuously built new campuses and hired additional staff over the past several years to accommodate the influx of students.
Planning for change
Districts with declining numbers of babies and new families have felt the drag on enrollment. They’ve cut thousands of jobs, often by not replacing employees who retire, and the recent campus closure decisions in Aldine and Houston ISDs illustrate the potential for more consequential changes.
Thrash said some districts are often well-prepared for enrollment shifts, armed with detailed demographic data from outside firms and in-house staffers who track trends.
Other districts, however, lack the resources to collect and accurately interpret the data driving enrollment trends.
“In an ideal world, it would be great if the Texas Education Agency or some kind of regional entity could provide regular, easy-to-understand data, so districts don’t have to shoulder that extra expense,” Thrash said. “The bigger concern, too, is making sure all districts have the support they need to interpret it and make the best decisions possible for their students.”
